The FCC voted to open 1,200 megahertz of spectrum in the 6 GHz band (5.925–7.125 GHz) available for Wi-Fi and other unlicensed uses. The 6 GHz band is currently populated by, among others, microwave services that are used to support utilities, public safety, and wireless backhaul. Unlicensed devices will share this spectrum with incumbent licensed services under rules crafted to protect those licensed services and enable both unlicensed and licensed operations to thrive throughout the band.
The new rules authorize indoor low-power operations over the full 1,200 megahertz and standard-power devices in 850 megahertz in the 6 GHz band. An automated frequency coordination system will prevent standard power access points from operating where they could cause interference to incumbent services.
The FCC expects its new rules to accelerate the adoption of Wi-Fi 6 and play a major role in the growth of the Internet of Things.
FCC Chairman Ajit Pai states: “Ultimately, I expect that 6 GHz unlicensed devices will become a part of consumers’ everyday lives. And I predict the rules we adopt today will play a major role in the growth of the Internet of Things, connecting appliances, machines, meters, wearables, smart televisions, and other consumer electronics, as well as industrial sensors for manufacturing. At the same time, our approach will ensure that incumbents in the 6 GHz band are protected from harmful interference. The microwave services that already use this band are critical to the operations of utilities, public safety, and wireless backhaul operations. And we are ensuring that those incumbents are protected by requiring the use of automated frequency coordination systems, which will only allow new standard-power operations in areas that will not cause interference to incumbent services, and by placing conservative power limits on low-power indoor operations.”
“By making 6 GHz available for unlicensed use, the FCC has secured the future of Wi-Fi. 6 GHz access is a seminal development for connectivity and provides Wi-Fi more capacity to deliver groundbreaking use cases and to unlock novel new Wi-Fi applications,” said Edgar Figueroa, president and CEO, Wi-Fi Alliance. “Today’s global climate highlights how important Wi-Fi is in connectivity and productivity, and new Wi-Fi 6E solutions will further increase Wi-Fi’s standing.”
